To wZZ whom it 'moty concern;

Be it known that LMEOKLEY MAsTEnsoN, a citizen of the United States, residing at Cripplecreek, in the county of Teller and State of Colorado, have invented a new and useful Oil-Gan, of which'the following is a specification. 1

This invention relates generally to oil-cans, and particularly to that class wherein the oil is forced from the can by suitable force-feeding mechanism.

The object of the present invention is to improve the construction of the force-feeding mechanism by reducing the number of its parts and at the same time increasing its capacity for doing effective work, to provide means whereby oil will positively be directed to the induction or feed pipe irrespective of the angle or tilt of the can-body, to improve the valve-casing whereby to permit its ready removal for purposes of cleansing or repair, and generally to improve the construction of the can as a whole.

With these and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction'and combination'of parts of an oil-can, as will be hereinafter described and claimed. v V

In the accompanying drawings, forming a part of this specification, and in which like numerals of reference indi'cate corresponding parts, there is illustrated one form of embodiment of the invention capable of carry ing the same into practical'operatiomit being understood that the elements therein exhibited may be varied or changed as to shape,

, proportion, and exact manner of assemblage without departing from the spirit thereof.

In the drawings, Figure 1 is a view in vertical longitudinal section of an oil-canconstructed in accordance with the present invention. Fig.- 2* is a View in vertical longitudinal section through 'the valve-casing.-

Fig. 3 is a view in elevation showing the different parts of the valve-casing separated. Fig. 4 is a view in horizontal section, taken on the line 3 3, Fig. 3, and looking in the direction of the arrow thereon.

Referring to the drawings, 1 designates the near the lower end of the tube-shank.

" body of the oil-can, which may be made of any suitable metal and furnished atits upper end with a spout-socket 2, provided with an inverted-dish-shaped head 3 to bear upon the upper side of the can and to be permanently associated therewith by a locking- Washer 4, engaging exterior threads arranged on the lower portion'of the socket and operating to clamp the can-body against the head 3, the washer beingassociated with the socket before the can-bottom is secured in place.

The socket is provided with a plurality of openings 5, through which oil is fed to the can as required, the openings being normally closed by the lower portion of a tube-shank 6. The shank has a threaded connection with thesocket and when seated engages a gasket 7 housedin the lower portion of the socket, and thereby positively cutsofi escape of oil through the openings 5. The tubeshank is provided with a knurled head 8, by which to facilitate removal of the shank from the can-body. The tube-shank has associated with it in any preferred manner, as by solder or the like, a tube or spout 9, which incloses a second tube 10, which operates to stifien the tube proper. The tube 9 has associated with its upper end a curved chambered nozzle 11, the terminal of whichislprovided with flutes or recesses 12 to pernciit escape of air when thenozzle is inserted in a tight-fitting oil-hole. Within the chamber 13 of' the nozzle is arranged a hemispherical valve 14, which bears upon'aiid closes the upper end of the tube, and connected with the under side of the valve isa wire 15, the lower end of which has connected with it or is formed into a coiled spring 16, secured at its free end to a transversely-disposed pin 16, arranged This valve operates topre'vent escape ofoilI'fro'm the nozzle under ordinary circumstances or when the can is accidentally tiltedor inverted,

'and also precludes entrance of air to the body of the can when the force-feeding mechanism,

, presently to be described, is operated to'lit'tthe oil from the can-body and direct it to the spout.

The force-feeding mechanism above referred to comprises a pump-barrel 17, per- ICO manently associated in any preferred manner with the can-body. Communicating with the underside of the pulnp-barrel is an induction or oil-feed pipe 18, the latter being approximately an inverted gooseneck in shape and projecting at its free end through a partition 19, constituting an oil-detaining device, inasmuch as it will prevent the oil confined between it and the front side and bottom of the can from rushing to the top of the can when the same is tilted or inverted, thereby always to insure a proper supply of oil to the induction-pipe 18. The partition, which will hereinafter be designated an oil-detainer, is secured to the can approximately about midway of its height and inclines from the front downward toward the rear of the can to a point within a short distance of the bottom, as clearly shown in Fig. 1.' The inductionpipe 18 projects some distance above the bottom of the pump-barrel, as clearly shown in' Fig.2, and has associated with it a valvecasing 20, the connection between the partsbeing such as to permit ready disconnection of the casing from the feed-pipe for purposes of cleansing or repair. The means for associating the parts consist in this instance in arranging within the valve'casing a springclip 21, spaced from the walls of the casing to occupy a position concentrically therewith by a block 22, through which passes a rivet 23 for holding the clip, block, and easing rigidly assembled. This clip, as clearly shown in Fig. 2, is adapted to engage frictionally with the upper end of the pipe 18, thus to hold the valve-casing in position thereon; but should it be necessary to remove the casing for either of the reasons above stated this may readily be effected by inserting a hooked or pronged instrument into the pump-barrel and engaging it with the walls of the oil-escape openings 24 in a casing. The upper end of the pipe 18 is closed by a valve 25, provided on its upper side with a nipple 26, which is engaged by one end of an inverted-cone-shaped spring 27, the upper end of which bears against a pin 28, passing transversely through the upper portion of the valve-casing. The form of spring herein shown for holding the valve 25 seated is one of many that may be employed, and for this reason it is to be understood that the invention is not to be limited to the precise arrangement shown. The pump-barrel is connected with the lower portion of the spout-socket 2 by a curved eduction or supply pipe 29, which discharges directly into the tube-shank, as clearly shownin Fig. 1. The valve-casing is of a diameter sufficiently less than that of the pump-barrel to permit ready discharge of the oil through the openings 24 of the valve-casing to the barrel and thence to the pipe 29.

The suction and forcing mechanism codperating with the pump-barrel comprises a piston 30 of the usual or any preferred construction,to which is pivotally connected one end of a link 31, the other end of which is pivoted to an operating-lever 32, pivoted to ahandle 33, suitably secured to the can-body, a spring 34, carried by the handle and bearing against the said lever, operating to cause the latter normally to occupy the position shown in Fig. 1 or in such relation to the pump-barrel as to cause the piston to be depressed when the lever is drawn back, the stress of the spring to be sufficient to cause the lever to resume its normal position after having been rocked by the operator.

The operation of the can is as follows: Upon the can being tilted for the purpose of permitting insertion of the nozzle into the oilholes of the bearing. or other part to be Inbricated the bulk of the contained oil will naturally rush to the upper end of the canbody, but a portion will be caught and retained between the oil-detainer and the front side and bottom of the can. The operatinglever being now rocked toward the handle, the oil in the pump-barrel dTawn there by a preceding stroke of the piston will be forced up through the eduction-pipe 29 and into the spout through which it passes, unseating the valve 14: in its passage and escaping through the nozzle 12, the valve 25 operatingto close the pipe 18, and thus prevent return of oil to the can-body. Upon release of the handlever the spring 34 projects it toward the canbody, thereby raising the piston, which latter in its upward movement creates a suction in the pump-barrel that operates to lift the valve 25 against the stress of the spring 27 and draw a fresh charge of oil into the pumpbarrel, the valve 14c preventing any air from being sucked through the tube into the bar rel,which would, of course, prevent the proper operation of the device. The operations of lifting and discharging the oil are very rapid and eifective, and by the provision of the valve 14 waste of oilis positively obviated, as the instant that the pump is stopped in its operation the valve will automatically resume its seat, and thus cut off the discharge of oil. Under the operation of the hand-lever oil may be forced from the nozzle in a stream or drop by. drop.

All of the parts of the implement are constructed with a view to simplicity, thoroughness of operation, and durability in use, and may be made in standard sizes, so that in the event of a part becoming damaged or broken it may readily be replaced.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
